Selection of tube length in the tube side of a shell and tube heat exchanger
Thread Content
For a shell and tube heat exchanger where the calculated value of L is 20, how should the length of the tube side and the heat transfer tubes be set? Can I use a tube side length of 4 with a tube length of 4.5, or must it be a tube side length of 4 and a tube length of 6?
If the technical requirements can be met, then choose the option that is more cost-effective based on cost considerations
Considering the pipe length, it’s cost-effective and practical!
What method are you using to calculate this? I’ve never seen a calculated pipe length of 20 meters. Isn’t the effect of 4 pipe runs at 6 meters different from that of 1 run at 20 meters? For a single-pass length of 20 meters, it should be fully counter-current; with 4 tube passes, there will be temperature cross-over.
